Installing openCFS

openCFS runs on Linux, macOS and Windows. Below you find instructions for your operating system.

Linux

We provide openCFS including all dependencies in a single archive. The software should run on any recent linux system.

To install, just download the most recent archive, e.g. the recent master build: CFS-master-Linux.tar.gz, and extract it to the desired location.

wget https://opencfs.gitlab.io/cfs/CFS-master-Linux.tar.gz
tar -xzvf CFS-master-Linux.tar.gz

This will extract to CFS-<SHA>-Linux where <sha> is the commit checksum of the installation. The executables are found in the bin directory of the installation, e.g. in the directory CFS-<SHA>-Linux/bin. You can add this directory to your PATH by running

export PATH=<absolute-cfs-installation-path>/bin:$PATH

To make this persistent add it to the configuration file of your shell, e.g. to ~/.basrc for bash.

You can now run cfs by

cfs -h

macOS

We provide openCFS including a subsection of dependencies in a single archive. For structural optimization you shall download the snopt and scip source from the respective code authors and compile openCFS yourself.

The provided binary is built with recent macOS (Intel) and not tested on former platforms.

For further help please follow the Linux instructions

Windows

For Windows we currently provide a portable installation of openCFS in form of a zipped archive; a dedicated Windows installer is currently in preparation.

The build is based on a recent snapshot of the openCFS master, version 21.03, as of 03/23/2021. Intel Parallel Studio XE 2020 and Microsoft Visual Studio 2019 have been used for the compilation and the build has been performed on Windows 10, Version 20H2, Build 19042.867. Only a 64 bit version of openCFS is available for Windows. The portable version comes without an installation of the runtime libraries for Visual Studio 2019; the installer VC_redist.x64.exe can be downloaded from Microsoft.

For the installation download the zipped archive openCFS_21.03_win10_x64.zip and unzip this into any location that you prefer, let’s say C:\Users\openCFS\21.03. Next, define the environment variable CFS_ROOT_DIR pointing to the top directory of your openCFS installation. Using the above folder this will result in CFS_ROOT_DIR=C:\Users\openCFS\21.03.

To run openCFS, open a command shell, eventually define CFS_ROOT_DIR, if you have not already done so, which in our example results in

set CFS_ROOT_DIR=C:\Users\openCFS\21.03

and execute CFS by typing %CFS_ROOT_DIR%\bin\cfs -h.

To simplify the execution of openCFS you might consider adding %CFS_ROOT_DIR%\bin to your PATH environment variable by

set PATH=%CFS_ROOT_DIR%\bin;%PATH%
